While setting up an authenticator app for 2FA you can view the setup key which we automatically generate as a QR code, but which can also be read in plain text by clicking on View setup key. It is sometimes also referred to as a "backup code" or "secret seed code".

The setup key can be manually entered into most authenticator apps to restore your 2FA. Please contact the developer of your app (e.g. Google, Microsoft, etc.) to find out how to do this.

If not securely stored, the setup key can be compromised and used to gain access to your account. Furthermore please do not share your setup key with anyone, including our Support team.A more secure alternative to writing down your setup key would be to set up a Master Key in a separate location and device, or by using a Hardware Security Key instead.
